Title: Image pickup device
Inventor: HIROSE HISANORI
IPC: H04N5/341
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To display a video image in an entire area or part of the area of an image pickup element having a wide light receiving area and to read a video image in the entire area at a frame rate as high as possible without increasing power consumption of the entire image pickup device. SOLUTION: The image pickup device uses a 2nd clock with a high frequency when reading a video signal from an entire light receiving area of an image pickup element 2 or uses a 1st clock with a low frequency when reading a video signal from part of the entire light receiving area of the image pickup element 2. Thus, the video signal in the entire light receiving area or the video signal of the part area is read and displayed. Even when a read rate to read the video signal from the entire light receiving area is set high to a degree, the entire power consumption of the image pickup device system is reduced.

Filed: 1981-07-24
Abstract: PURPOSE:To obtain the I<2>L semiconductor device, power consumption thereof is reduced, by forming the first conduction type floating region into the second conduction type semiconductor layer just under the first region and controlling reactive currents. CONSTITUTION:The P layer 8 in floating form is shaped into the N layer 3 just under the P region 4 functioning as an injector.
